The Lovato GLCMB0200A230UL is a high-performance motorised three-pole changeover switch certified to UL 1008, providing safe and reliable automatic transfer between two independent power sources. Designed for standby generator systems, automatic transfer switch (ATS) panels and mission-critical electrical installations, it delivers dependable switching performance for commercial, industrial and infrastructure applications.
As part of the advanced Lovato GLCM UL series, this model combines a robust mechanically interlocked switching mechanism with a motor-operated drive, ensuring controlled break-before-make operation between utility and emergency power supplies. Its compact construction simplifies installation while maintaining excellent durability and long mechanical life.
Featuring a 200 A UL general purpose current rating, 208–277 V AC motor operating voltage and a three-pole configuration, the GLCMB0200A230UL is ideally suited for demanding automatic transfer applications where uninterrupted power availability is essential.
The GLCMB0200A230UL uses a motor-driven break-before-make switching mechanism that safely transfers electrical loads between two independent power supplies. During every transfer, the load is disconnected from the active source before the alternate supply is connected, preventing parallel connection of both sources and ensuring safe operation.
Certified to UL 1008, the switch is specifically designed for transfer switch applications requiring high reliability, making it suitable for commercial buildings, healthcare facilities, industrial plants, data centres and other critical power installations.
